[NTDP] Goal clarification

["John Zaharychuk" <[e-mail]>]

Morning,
 
I have read through the introductory details posted by Craig and they
raise a few points that I would like to discuss.
 
The example testbed described utilizes four different devices to
generate the combined test traffic required for the test. Each of these
devices generates a different type (or types) of traffic.  While I can
see a desire to have common commands and scripts across devices that
perform identical functions, I am less clear as to how commonality can
be achieved across different services. The configuration data for a
Voice Call and the collection of MOS metrics is different than the
configuration data for an FTP file transfer and the collection of
throughput metrics. These differences are independent of the fact that
different devices are being used. The same differences would exist if a
single superset device was used. Granted, each device that connects to
the network shares some common network configuration, but it is the
service configuration where the complexity lies. 
 
Maybe the goal is to create a common "form" or syntax for the
configuration data across both services and devices. It could shorten
the learning curve for the tester, but would not eliminate the need to
understand the different services and metrics.
 
I look forward to a better understanding and further discussions.
